There's speculation and there's fact. It would be a pity if rational discussion as to the causes of this tragedy were suppressed simply because they turned out to be somehow politically awkward. So far all we know is the guy had a history of mental instability and was a long term member of a group expressing fairly extreme right wing racial views. Neither in isolation might be regarded as dangerous but in combination might have proved the trigger for this terrible event. Since the perpetrator is still alive its entirely possible his motivation [ however twisted his logic] for this senseless act may yet emerge under questioning.
